Earlier quoted context omitted.
I am probably stupid so bear with me. I don't get the part about not naming brands if you are certain they won't ever sponsor you. I feel like it just hurts the value of the article with nothing gained
It's not about sponsorships and integrity, it's about preventing the pipeline "Person reads article -> Sees this brand of vape has micocontrollers -> Buys this brand of vape". (If I understood the author correctly, y'know, not to speak for them)
With your example, why would the author care whether some random person buys the vape he mentioned in his article? I don't see the point
